Usually elastomers are a synthetic nonmagnetic (composite, high-molecular) materials that can easily and reversibly change their form or size under the external influence –- thermal, mechanical or field. If some elastomer contains magnetic, mainly ferromagnetic, particles, then it responds to the external magnetic field. Thus, it is referred to as magnetoactive elastomer (MAE) [1]}, [2]}. The magnetic field affects MAE through its magnetic subsystem, understandably [3]}, [4]}, [5]}, [6]}, [7]}. MAE can not only be deformed, even substantially, by tens of percent, but also can change its physical properties and characteristics [8]}, [9]}, [10]}, [11]}, [12]}, [13]}. The change of MAE elastic modules has been defined as the magnetorheological effect (MRE) [14]}, [15]}, [2]}, [17]}, [18]}. Due to all their abovementioned properties, MAE are now classified as smart materials [19]}, [20]}.
